/* Form 1 instructions come in different flavors: |
|
Some have no arguments (MOXIE_F1_NARG) |
Some only use the A operand (MOXIE_F1_A) |
Some use A and B registers (MOXIE_F1_AB) |
Some use A and consume a 4 byte immediate value (MOXIE_F1_A4) |
Some use just a 4 byte immediate value (MOXIE_F1_4) |
Some use just a 4 byte memory address (MOXIE_F1_M) |
Some use B and an indirect A (MOXIE_F1_AiB) |
Some use A and an indirect B (MOXIE_F1_ABi) |
Some consume a 4 byte immediate value and use X (MOXIE_F1_4A) |
Some use B and an indirect A plus 4 bytes (MOXIE_F1_AiB4) |
Some use A and an indirect B plus 4 bytes (MOXIE_F1_ABi4) |
|
Form 2 instructions also come in different flavors: |
|
Some have no arguments (MOXIE_F2_NARG) |
Some use the A register and an 8-bit value (MOXIE_F2_A8V) |
|
Form 3 instructions also come in different flavors: |
|
Some have no arguments (MOXIE_F3_NARG) |
Some have a 10-bit PC relative operand (MOXIE_F3_PCREL). */ |
